When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat

We report on the interfacial behaviour of a series of nonionic diblock copolymers at solid hydrophobic and hydrophilic surfaces/water and silicone oil/water interfaces, studied by ellipsometry. The polymers consist of a hydrophobic C-18 chain linked to a hydrophilic poly(ethylene oxide) (PEO), block varying from 50 to 250 U. The adsorption of these copolymers at low bulk concentrations was found t

Most methods that guide the designer through the later phases of the design process are general in nature, and it is up to the designer to organize the design work using the tools and techniques available. This process also relies greatly on experience, which is quite a challenge for students, who are mostly novices in the area. In a comparative study, the evolution of the experience and skills ac

An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give provide incentive to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national i

Availability of safe, edible food is essential. Food shortage has caused many wars and encouraged people to try to preserve food for a longer time, allowing storage and transport, often in some kind of package/container. The USA showed the way in developing the food sector and already prior to the 2nd World War they had self-service stores filled with packed goods. Europe, however, had to wait to

Fashion's universal nature does not preclude strong variations in its significance from society to society. As a stratification variable, fashion's importance increases in step with economic growth. Simmel sees the ‘need for distinction’ and the ‘need for union’ as preconditions for fashion, with certain societies lacking the necessary motivation. Variations in fashion's importance have also been

Personal impressions of professor Gudmund smith as examiner, teacher and scientific supervisor in the late 1960:ies are presented.
